bilby.gw.conversion.lambda_1_lambda_2_to_lambda_tilde(lambda_1, lambda_2, mass_1, mass_2)[source]

Convert from individual tidal parameters to domainant tidal term.

See, e.g., Wade et al., https://arxiv.org/pdf/1402.5156.pdf.

Parameters:
lambda_1: float

Tidal parameter of more massive neutron star.

lambda_2: float

Tidal parameter of less massive neutron star.

mass_1: float

Mass of more massive neutron star.

mass_2: float

Mass of less massive neutron star.

Returns:
lambda_tilde: float

Dominant tidal term.
